Title: Improvements in or relating to reduction products of hydroxyisoquinolines
IPC: C07D217/04
Filed: 1966-05-20
Abstract: 1,144,246. Reduction products of hydroxyisoquinolines; penicillin salts. MARION LABORATORIES Inc. 20 May, 1966 [16 July, 1965], No. 22694/66. Headings C2A and C2C. Novel compounds of the Formulµ I, II or III wherein R 1  represents an alkyl group having not more than 8 carbon atoms, R 2  represents hydrogen or an alkyl group having not more than 8 carbon atoms, R 3  represents hydrogen or a benzoyl group optionally bearing up to 3 substituents which may be alkyl or alkoxy groups having not more than 8 carbon atoms or halogen atoms, and their acid addition and quaternary ammonium salts, are made by catalytic hydrogenation of the corresponding hydroxyisoquinolines, the typical catalyst being platinum oxide in the presence of glacial acetic acid. These compounds can be used in the isolation and purification of penicillin, with which they form salts. 5-Hydroxy-2-ethylisoquinolinium bromide is prepared by treating 5-hydroxyisoquinoline with excess ethyl bromide.

Title: Thermoplastic laminates
Inventor: SANDIFORD DENIS JAMES HENRY
IPC: B29C65/10
Filed: 1965-05-28
Abstract: 1,081,547. Laminated thermoplastic films. IMPERIAL CHEMICAL INDUSTRIES Ltd. May 13, 1966 [May 28, 1965], No. 22772/65. Heading B5N. A laminate is produced by feeding a thermoplastic film over a controlled temperature roller, locally heating the surface of the film not in contact with the roller by a flame of more than 1500‹ C. for a time sufficient to melt the surface of the film but insufficient to distort the film, and before the surface of the film has cooled to a temperature at which it will not bond to a substrate, sealing the film to the other component of the laminate. Suitable thermoplastic materials are polypropylene, polyethylene, polyesters, polyamides and polyvinyl chloride, and the films may be uniaxially or diaxially oriented. The second component of the laminate may be another thermoplastic film, and in this case the flame may be applied at the nip between two rollers affecting the surface of each film equally. Particularly preferred laminates have one film oriented in the machine direction and the other oriented in the transverse direction.

Title: Connecting device
IPC: B60P7/08
Filed: 1963-06-07
Abstract: 1,055,282. Strainers. R. E. JELLISON. June 7, 1963, No. 22809/63. Heading F2G. [Also in Division E2] A connecting device comprises a strap 22, a ring 24 and a pair of parallel rods 34, 36 located at a fixed distance from each other, the rod 36 constituting an anchor rod, the strap being anchored to said anchor rod and extending therefrom towards and around the rod 34 so as to form a first layer therearound through the ring and back on itself so as to pass around the rod 34, to form an inner layer therearound between the first layer and to leave a free end of strap the arrangement being such that when tension is applied between the ring and the rod 34 slippage of the strap is prevented by pressure exerted by the first layer on the inner layer of strap on the rod 34. In the construction shown the rods are mounted on a common frame 20 to which a lever 40 is pivoted on an axis parallel to the rods the lever being movable from a position wherein the lever extends generally in the direction of the rods to another position in which the lever extends away from the rods; the lever is provided with a hitch 46 in the form of a rod carried between two side arms of the lever to which another member 56 such as a hook or strap may be hooked, the location of the hitch 46 relative to the pivot being such that when tension is applied through the connecting device by way of the hitch the lever always tends towards one or other of its two positions. The free end of the strap 20 passes over a roller 50 mounted at the free end of the lever and pulling on the free end pulls the lever to the left as shown, this increasing the tension applied between the member 56 and a member 52 connected to the ring 24 and since the hitch 46 passes over the line connecting the axes of the rod 34 and the lever the lever remains in the tensioning position. The rod 34 is also provided with a roller.

IPC: C08F22/00
Filed: 1960-06-30
Abstract: A process for preparing thermosetting resins comprises reacting formaldehyde with an addition salt of a polyamine and an ethylenically unsaturated mono- or dicarboxylic acid or a monoester of an ethylenically unsaturated polycarboxylic acid copolymerized before or after salt formation with at least one ethylenically unsaturated monomer.  The polyamine may be melamine or ethylene diamine.  Specified acids are acrylic, methacrylic, crotonic, maleic and fumaric acids.  The comonomers may be alkyl acrylates, methacrylates, maleates or fumarates, styrene, vinyl acetate or acrylonitrile.

The condensation with carbonic acid esters, e.g. diethyl carbonate may be effected in the presence of an alkaline condensing agent, e.g. alkali metal alcoholates, hydrides or amides.  Hydrogenation of the 14 : 15-double bond may be effected using a palladium catalyst on charcoal, calcium carbonate, barium sulphate or zinc carbonate. The enol esters are produced with acid anhydrides or acid halides. Hydrogenolysis of the enol derivative is effected in neutral or weakly alkaline conditions in the presence of noble metal catalysts or Raney nickel.  Subsequently the enol ether group between the 18 and 11 positions may be split by known methods. Specification 814,711 is referred to.

The invention is described with reference to an apparatus for precipitation of calcium saccharate from solutions of molasses by the addition of quicklime. As shown (Fig. 1) quicklime is supplied by line 40 and molasses solution by line 56 to the upper portion 32 of agitator 30 within vessel 12. The reaction mixture in the bottom of vessel 12 is circulated by pump 72 and line 74 to the agitator (Fig. 2) where it enters chamber 114 and flows rapidly through passage 104. This draws the lime and molasses through from the upper part of the agitator and provides intimate mixing. Reaction mixture is also drawn from the upper part through slits 90; the upper level of the reaction mixture is arranged to be just below the top of the agitator.

Filed: 1958-07-23
Abstract: 856,886. Centrifugal pumps. BELL & GOSSETT CO. July 23, 1958, No. 23659/58. Class 110 (1). The self-priming centrifugal pump shown differs from that disclosed in Fig. 3 of Specification 856,885 in that the upper shroud 38 is extended so that its discharge end is in substantially the same vertical plane as the impeller axis, and the pump inlet is not provided with an anti-siphoning check valve. The discharge from the shroud 38 forms a liquid curtain that seals the open passage 46 against return of air into the impeller. When the pump is stopped, air can return through the passage 46 to break the siphon quickly and limit the loss of the priming reserve of liquid from the pump casing. The discharge end of the lower shroud 39 is substantially tangential to the concave bottom of the pump casing so that its discharge forms a cleansing stream that sweeps across the bottom of the casing. In other respects the pump is similar to that disclosed in Specification 856,885.
